I will be heading out next week on my first multi-day camping excursion with my 2011 Rockwood Roo 233s. The water heater is bypassed now, because of the winterization process - the pros did it for me using antifreeze.

Of course, I plan to push all the antifreeze out of the pipes before I reverse the bypass.

But my question is this: when needed, how the heck do I reach those bypass valves? From the outside of the trailer, it seems like I would have to crawl into the storage door to reach them. I need to look again, but from inside the trailer, maybe the storage/cabinet doors under the sofa or the bed would allow me to reach the valves?

On the 233S you will need to swing the back of the couch over like you are making the bed. Pick up the front of the bottom cushion on the couch & I will lift up as it is on a hinge. You can see the water heater to the front left behind a false wall. The bypass valves are within easy reach using this method. There are 3 ways to access that front storage compartment, outside, through the inside door & by lifting the bottom cushion which allow full access to everything under the couch storage area.

With my Grey Wolf 28BH I made a turn key from a piece of wood 2" X 7/8" onto which I attached 2 cleats extending beyond the length of wood about 2". This fits over the water heater valves and easily turns them. The length of this device reaches from outside the trailer through the storage compartment door which is on the opposite side of the wh. This saves me from lifting the queen bed and removing the small panel to gain access to the wh. Crawling through the storage compartment door along the full width of the trailer was not an acceptable alternative.
